ABSTRACT

A new  Erysimum  plant named ‘ERFZ0001’ particularly distinguished by the purple-violet flower color, medium green foliage color, rounded and compact plant habit with good branching and is early to flower.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Erysimum linifolium

VARIETAL DENOMINATION

‘ERFZ0001’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Erysimum, botanically known as Erysimum linifolium, and hereinafter referred to by the variety name ‘ERFZ0001’.

‘ERFZ0001’ is a product of a planned breeding program. The new cultivar ‘ERFZ0001’ has purple-violet flower color, medium green foliage color, rounded and compact plant habit with good branching, and is early to flower.

‘ERFZ0001’ originates from a hybridization made in a greenhouse in April 2009 in Enkhuizen, The Netherlands. The female parent was a commercially available plant identified as ‘Bowles Mauve’, unpatented, with mauve flower color, fewer branches, and overall larger size than that of ‘ERFZ0001’.

The male parent of ‘ERFZ0001’ was an unpatented, proprietary plant identified as ‘M1702-82’ with dark lilac flower color, is later to flower and less vigorous than that of ‘ERFZ0001’. The resultant seed was sown in September 2009 in a greenhouse, in Enkhuizen, The Netherlands.

‘ERFZ0001’ was selected as one flowering plant within the progeny of the stated cross in April 2010 in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘ERFZ0001’ was accomplished when vegetative cuttings were propagated from the initial selection in the April 2010 in a controlled environment in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in April 2010 in Enkhuizen, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘ERFZ0001’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘ERFZ0001’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length.

Plant Breeder's Right for this cultivar were applied for at the Community Plant Variety Office on Oct. 25, 2012 (2012/2346) and in Canada on Apr. 19, 2013 (13-7998). ‘ERFZ0001’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Erysimum as a new and distinct variety

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘ERFZ0001’ with colors being as true as possible with an illustration of this type. The photographic drawing shows in FIG. 1 a flowering plant of the new variety and in FIG. 2 a close-up of a flower and buds.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in March 2013 under natural light. These plants were growing in an outdoor trial under natural light in Gilroy Calif. The plants were about 24 weeks of age.
